ASH-SIFTER.

Specification of Letters Patent. Patented Aug. 31, 1920.

Application filed March 20, 1920. Serial No. 367,437.

To all whom it may concern:

Be it known that I, Isroon LUNENFELD, residing at 46 Colbourne street, in the city of Brantford, in the county of Brant, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Ash-Sifters, of which the following is the specification.

My invention relates to improvements in ash sifters, and the object of the invention is to provide'a simple construction of sifter which will be efficient in operation and which will be absolutely dust proofand it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Figure 1 is a sectional View through my sifter. v a

Fig. 2, is an end elevation.

In the drawings like characters of reference indicate the various parts in each figure. 1 indicates an ash container, the top 2 of which is provided with inclined side por-V tions 3 and 4. The'end walls of the con tainer also incline upward at their upper edge to conform with the incline of the top side portions 3 and 4, terminating at each side of the center of the container so as to form a cross slot 5. Near the apex ofr the end portions 6 of the container I provide bolts 7. p v

8 is a sifter which is in the form of a rectangular casing having its bottom inclined downward from each end at 9 and 10 so as to form a center cross slot 11. 12 is a cylindrical portion formed integral with the portions 9 and 10 the upper portion of such cylindrical portion 12 being slotted to correspond with the slot 11. V

13 is a slot formed in the lower portion of the cylindrical portion 12. The cylindrical portion 12 is mounted at its ends upon the bolts 7, so as to swing thereon with the outer periphery of such cylindrical portion 12 remaining in contact with the side edges of.

the slot 5 formed by the portions 8 and 4 of the ash container 1. f

14is a flap closure for the open end of the sifter 8. 16 is a sieve secured in the sifter 8 so as to extend over the bottom portions 9 and 10 and the slot 11. When it is desired to sift the ashes the sifter 8 is thrown into an inclined position so that theflap 14 is 7 presented upward." The flap 14-is secured a in position by suitable fasteners 17 and these fasteners which may be in the form of hooks are then swung aside and the flap 14 opened and the ashes deposited within the sifter. The closure 14 is then reclosed and the sifter 8 oscillated on the bolts 7 so that the ashes are thrown from end toendof the sifter 8 upon the sieve16. The ashes fall down through thesieve and pass through the slots 11 and 18 into the ash container 1.

It'may be readily understood that by my construction an absolutely dust proof joint is formed between the sifter Sand the ash,

joint closed during the rocking operation of the sift'er' 8. When the ashes have been container 1 by means of the slottedcylinder '12 which, rocking in the slot 5, holdsthe 7 sifted, the sifter 8 is inclined downward so that the closure 14 is presented downward.

Such closure is then opened to allow the 1 provided at the apex with aslot, the side walls of said slot being formedto project above the topand to present opposed concave bearing surfaces, a sifter having the 7 I body portion thereof formed to present a slotted horizontally disposed tubular extension, said extension being disposed for oscil-V I surface thereof in sliding 'contact'with: the

opposed bearing surfaces ateither'side of the slot, and pivots supporting the end fiof'. said extension in said slot, said pivots beingpositioned midway between the sides of the caved bearing -lating'movement in said slot withthe outer' lot and ma plane with the opposed con-
